NationMaster - Encyclopedia: Hurricane Allen

Hurricane Allen was the strongest hurricane of the 1980 Atlantic hurricane season. It was one of the strongest hurricanes in recorded history, one of the few hurricanes to reach Category 5 status on the Saffir-Simpson Hurricane Scale on three separate occasions, and spent more time as a Category 5 than any other Atlantic hurricane. Allen is one of only two hurricanes in the Atlantic to achieve 190 mph winds, the other being Hurricane Camille. The Saffir-Simpson Hurricane Scale is a scale classifying most Western Hemisphere tropical cyclones that exceed the levels of tropical depression and tropical storm and thereby become hurricanes. ...

Storm history

Allen originated as a Cape Verde-type hurricane, a rarity for tropical systems in early August. As it moved towards the Caribbean it became the first named storm of the season. Allen sped westward, rapidly intensifying into a Category 5 hurricane and (very unusually) remaining so for over a day. The eye passed just south of Hispaniola and just north Jamaica as a Category 4 hurricane.^{[citation needed]} Image File history File links Download high resolution version (1024x633, 451 KB) Summary Hurricane Allen (1980) track. ...

After weakening from interactions with the mountains of Haiti and Jamaica, Allen reintensified to a Category 5 for a second time, again retaining this intensity for over a day. It moved between Cuba and the Yucatán Peninsula. Interestingly, during Allen's trek through the Caribbean Sea and the Gulf of Mexico, its center of circulation never crossed over land despite its close passage to the islands of the Caribbean.^{[citation needed]} The YucatÃ¡n Peninsula separates the Caribbean Sea from the Gulf of Mexico. ...

Allen again weakened to a Category 4 storm through interactions with land, but it restrengthened into a Category 5 hurricane for a third time as it moved over the warm waters of the Gulf of Mexico, again keeping this intensity for nearly a full day. Shortly before landfall, dry air aloft in the Gulf caused the massive storm to weaken substantially. Allen made landfall north of Brownsville, Texas as a Category 3 storm with sustained winds of only 115 mph.^{[citation needed]} Hurricane Wilma, the most intense hurricane ever recorded in the Atlantic basin, devastated parts of the YucatÃ¡n Peninsula and southern Florida during October in the 2005 Atlantic hurricane season. ...

Allen caused extensive damage in both Hispaniola and Jamaica. Hurricane-force winds were reported in both Cuba and the Yucatán Peninsula, along with gale-force winds in the Florida Keys.^{[citation needed]} Early map of Hispaniola The island of Hispaniola (from Spanish, La EspaÃ±ola) is the second-largest island of the Antilles, lying east of Cuba. ...

In Texas, the storm surge was reported as high as 12 feet at Port Mansfield, though it may have been higher because the highest surges occurred in unpopulated and unmonitored sections of the Texas coast. A peak wind gust of 129 mph was also measured at Port Mansfield. The storm caused 7 deaths in Texas and 17 in Louisiana (most resulting from the crash of a helicopter evacuating workers from an offshore platform). Allen spawned several tornadoes in Texas. One tornado caused $100 million in damage when it hit Austin, Texas, making it the costliest tropical cyclone-spawned tornado ever. Overall, however, the storm caused limited damage in the United States due to its suddenly diminished power and because its highest tides and winds hit a sparsely-populated portion of the Texas coast.^{[citation needed]} Official language(s) None. ... ...
